If you use a true "coil over" shock, then the stock spring and strut are thrown away. If you simply replace the struts, then the spring is re-used.

If you're only increasing weight by 250 lbs over stock, then I'd suggest replacing the struts with Bilstein Heavy Duty (which are equal to the upgraded M030 struts) and re-use the stock spings.
